The potential for users to register multiple accounts is inherant in FB's architecture. FB has compounded their problem by creating incentives for users to have multiple accounts (hosting cooperative games like Farmville, for instance). FB cannot restrict users from creating multiple identities without undercutting the simplicity, openness and flexibility that draws people to FB in the first place.

IMHO, they should consider it a feature, not a bug. The alternative is going to be a much more limited FB architecture and a huge exodus of users and content providers.

Several of my friends had multiple accounts for exactly that reason. Not so much CHEATING at Farmville, but one account for games, one account for everything else, to keep down some of the spam to their personal feed.

There’s a Catbook app (with variants for basically every beastie I’ve ever seen kept as a pet, including rodents and ferrets) for those doing “pet pages” tho. Much easier than a separate signin.
